38198 2010-04-27 07:25:26 -0700 <symbol> tooltips not displayed 2010-04-27 10:11:39 -0700 1 1 1 Unclassified WebKit SVG 528+ (Nightly build) All All RESOLVED WORKSFORME http://upload.wikimedia.org/wikipedia/commons/5/50/Weather-icons.svg P2 Normal --- 1 jay webkit-unassigned jeffschiller krit zimmermann oldest_to_newest 217687 0 jay 2010-04-27 07:25:26 -0700 iirc in every case, where there is a title a tooltip should be raised. in case of more than one, within an open element only the first is used. furthermore and in particular, <use> can reference any named svg resource, ie does not require symbol, g or any other specific element. there is no requirement or expectation that <g>** should be used to enclose titles. **for the singular case where <g> is used, and a title is raised see: https://bugs.webkit.org/show_bug.cgi?id=16854 there has been some debate, about hierarchies of titles, but that is not part of this bug. please check the specs as this is from my poor memory of 6 years ago, or more.... 217698 1 jeffschiller 2010-04-27 07:35:20 -0700 Someone please update the following since the person who raised this did not follow instructions at https://bugs.webkit.org/show_bug.cgi?id=16854#c32 * Please update abstract/title to "Symbol tooltips not being displayed" * Please clear the "HasReduction" keyword (there is no test case attached) * Please clear the "EasyFix" keyword since this is not an easy fix 217716 2 jay 2010-04-27 08:41:32 -0700 Jeff, this bug does not relate to <symbol> however that is a testcase, and is in the URI given apologies if this is not an easyfix, hard to guess, as the one fixed evidently was.... 217721 3 jeffschiller 2010-04-27 08:47:13 -0700 Jonathan - please submit a reduced test case that demonstrates your problem in WebKit trunk. Otherwise it is difficult to understand what you feel doesn't work. As far as I know, the only thing that doesn't work is <symbol>. Thanks. 217723 4 jay 2010-04-27 08:50:01 -0700 Jeff, you intimated that <g> was needed, this is irrational, but doesn't suggest that everything else works, rather the reverse... 217724 5 jeffschiller 2010-04-27 08:50:41 -0700 Jonathan - please submit a reduced test case that demonstrates your problem. 217731 6 jay 2010-04-27 09:09:51 -0700 Jeff, the test case is the URI, your test case for the previous bug was not helpful, as explained, and you failed to indicate that <defs> <line id="sunny" style="stroke-width:17;stroke:#f0f" x1="22" y1="75" x2="139" y2="75" > <title>line</title> </line> </defs> <use xlink:href="#sunny" x="33" y="72" /> was fixed, either in the comments, or testcase, it's not clear to me why symbol should be treated differently to g, and hence why this is not an easyfix. 217733 7 zimmermann 2010-04-27 09:17:45 -0700 (In reply to comment #6) > Jeff, the test case is the URI, > > your test case for the previous bug was not helpful, as explained, and you > failed to indicate that Jay, this is not a way to talk to hard-working contributors. The testcase is NOT THE URI. A reduced testcase is needed, as simple as possible. > <defs> > <line id="sunny" style="stroke-width:17;stroke:#f0f" x1="22" y1="75" x2="139" > y2="75" > > <title>line</title> > </line> > </defs> > <use xlink:href="#sunny" x="33" y="72" /> > > was fixed, either in the comments, or testcase, No one has time to look through complex testcases, you should reduce it, and upload it here. > > it's not clear to me why symbol should be treated differently to g, and hence > why this is not an easyfix. You have no understanding of our internals, so it's hard for you to judge what is hard to fix and what not. Upload a reduced testcase, and someone will be able to investigate. 217735 8 jeffschiller 2010-04-27 09:22:46 -0700 You might want to read http://webkit.org/quality/reduction.html The URL you have submitted is not a reduced test case - it is a Wikimedia commons-hosted file for showing weather symbols. That file has 24 <symbol> elements and 18 <use> elements and no instructions on how to reproduce the problem you see. Please remove HasReduction keyword if you are able. My test case for Bug 16854 https://bug-16854-attachments.webkit.org/attachment.cgi?id=53317 is concise, has instructions and demonstrates a variety of scenarios in which tooltips on SVG elements now work. As I tried to state at https://bugs.webkit.org/show_bug.cgi?id=16854#c32, the only scenario that doesn't work is when the use references a <symbol> with a <title>. Thus, I had to rework the Wikimedia file as I discussed as a demonstration of a workaround. The details of why this doesn't work have nothing to do with the spec or users perceptions - they have to deal with the WebKit code. The details I believe are that <symbol> is not treated as a visible element (as per spec). As a consequence it is not iterated over when doing the hit-test for mouse hovering. If I could have fixed this for 16854, I would have.
